What is the Pro Angler's normal/ average cruising speed?...And what is it's top hull speed?...I ask because I timed myself once, over a 2 mile distance peddling at a comfortable speed for myself, and it took 30 minutes so I estimated my speed at about 4 mph...But I didn't take into account wether I was peddling with, or against the tide and I also had a head wind of about 5 mph. Going back in, the wind had changed direction to continue to blow against me about the same speed or 5 mph, but it took me about 1.5 times as long to get back...

Also, I went to a website where they had a formula for determining a boat's top hull speed, and from using their formula the resulting top hull speed for the PA was a little over 5 mph...But that doesn't seem correct...That seems a little bit slow?...Are there any engineers out there, or on Hobie's staff that can answer my question?

Everybody's cruise speed is different depending on fins, power applied and distance. It could be 3 MPH fore some and 4.5 MPH for others. The usual displacement hull speed formula doesn't really apply to kayaks since they're not really displacement hulls. Length to width ratios, weight, etc also make a difference. So there is no hard and fast rule. The PA can be sprinted to over 6 MPH.
